Session cookies do not collect your personal data and are deleted when your browsing session ends. Stored cookies — cookies that do track your online preferences, like login credentials, in order to improve your website experience. Stored cookies will expire after some time has passed.

Third-party cookies — the cookies that track you. Third-party cookies collect your data when you visit a website and may be shared with or sold to third-party advertisers. Clearing your history doesn't usually clear the cache, and clearing the cache doesn't delete the history.

Unlike cache and history, cookies are packets of saved information that are created by the website you visit, not by your web browser. Cookies are usually designed to help identify you when you return to visit. For example, if you log into a website you've previously used, it can identify that you already have an account and which pages you visited — and it will sign you back in automatically.

Most legitimate websites today notify you when they use cookies, and many will give you the option to accept cookies or not. Sometimes, it's not the website itself that uploads cookies to your computer, but advertisers on the website. These are known as third-party cookies, which may track other websites you have visited. An advertiser, for example, may use these cookies to determine what your interests are to optimize which ads it shows you.

Cookies may remain on your computer for any period of time, ranging from a few minutes to a couple of years. Clearing your browser history, cache and cookies can protect your privacy, especially if you share your computer with others. They will no longer be able to quickly see which websites you have visited. Deleting your cache and history may clear up some room on your computer or mobile device, particularly if there are a lot of images or even videos stored to your cache. In some cases, clearing or deleting cookies can solve performance issues when you visit a website, particularly if the cookie is flawed.

While it may affect your surfing experience, this isn't usually in any significant way.
